T 0- all whom it may concern:

Beit known that we, Tony NEWMAN and IRA MARTIN DAVIDSON, both citizensof the United States, residing at Los Angeles, in the ing ring tomaintain said tire on the rim of the wheel.

The object of this invention is to provide an improvement whereby thelocking ring may be readily contracted and expanded and positivelylocked in its expanded position.

, Another object is to provide for tightly closing the joint without theuse of nuts,

washers, or packing of any kind I 'The accompanying drawings illustratethe invention.

V Figure 1 is a fragmental elevation of a vehicle-wheel embodying thisinvention. Dotted lines indicate the contracted position of the openlocking-ring. Fig. 2 is a fragmental cross sectional view illustratingthe inven tion. Fig. 3 is a view showing the locking ring detached andsomewhat contracted. Dotted lines indicate the expanded position. Fig.dis an enlarged fragmental detail from the inside of the open ringshowing the parts. in locked position.

the wheel.

3 designates inwardly-projecting ears at a distance from the ends of theopen ring.

4, 5'designate two members of a toggle device pivoted respectively tothe ring at a distance from the ends thereof for contracting, expandingand locking the ring, said members consisting in a link 4, pivoted atone end to the'other one of the ears 3, and pivoted I also intermediateits ends totheend of the link 4. Said member-5.11s preferably curved toconform to the inside'ofntheopen rin and is provided with a wedgeepieceor look member 6, adapted to tightly wedge between the ends of the ringto fit in and close the open space between said rings, and to make atight oint and take off the strain from the pivots of the toggle joint.

7 designates the handle portion of the member 5, and 8a locking devicein the form of a button appropriately mounted. by being fastened to thering 2 and adapted to engage the handle, thusto hold the member 5 andits wedge-piece 6 in locked position. The link 4 and toggle member 5 arebent or broken jointed, as indicated in Fig. 4, so that when the toggleis in locked position it's midpivot 9 will have passed a line drawnbetween the end pivots 10, 1 1 of the toggle, and

the wedge-block operates positively to expand the ring and hold is so aslong as the handle is locked by the locking device.

In practical use the labor of applying and removing the 0 en lockingring to and from the rim of thew eel is reduced to a minimum and isperformed by simply releasing the button 8 andswinging the member 5toward the center of the locking ring, thus contractin said lockingring',,whereby it may be inserte into or Withdrawn from its engagementwith the beaded rim of the wheel. When the looking rin has been thuscontracted and then inserte I, into the vehicle rim, the toggle handle 7may then be pressed outward toward the ring 2, thereby 5 reading theends of the open ring apart nnti the pivot 9 of the togglehas passed theline drawn between the pivots 10 and 11, and the block 6 has entered andwedged in between the ends of the open ring 2. Thereupon the curvedhandle 7 will come to rest against the inside of the open ring, andthereupon the locking device 8 may beturned thus to engage the handle 7and cking position.
